Question

PLEASE HELP

If the domain of a relation is all whole numbers between 2.5 and 7.5, and the range contains 6 different values, can you determine whether the relation is a function? Explain your reasoning.

Answer 1

The person above me has the right answer to your question:)

Answer 2

"This relation is not a function as the domain has fewer values than the​ range, so there must be a domain value which maps to more than one range value."

Explanation:

If each element of the domain has a unique value inside the range, the relation is said to be a function.

A relation's domain is a collection of all whole numbers in the range of 2.5 and 7.5, with a total of 6 distinct values.

The range of whole numbers from 2.5 to 7.5 is 3, 4,5,6,7

There must be a domain value that maps to more than one range value since this relation is not a function because the domain contains fewer values than the range.
